          Returns an ``int`` denoting which game is played for the team during
          the given day. Default value is 1 where a team plays only one game
          during the day, but can be higher for double headers, etc. For example,
          if a team has a double header one day, the first game of the day will
          return 1 while the second game will return 2.
